Podshipnik uchun Qopqoq tanlash
Podshipnik tashqi diametriga qarab jadvaldan unga mos qopqoq o’lchamlarini ko’chirib, shular asosida qopqoq yasaymiz.
Qo`shimcha valdagi podshipnik uchun: qopqoq;
D=62; D<sub>1</sub>=75; D<sub>2</sub>=95; D<sub>3</sub>=52;
d=7; d<sub>1</sub>=12; d<sub>2</sub>=14; n=4
H=10; H<sub>2</sub>=22; h<sub>1</sub>=7; b=5;
1-podshipnik uchun
D=62; D<sub>1</sub>=75; D<sub>2</sub>=95; D<sub>3</sub>=52;
d=7; d<sub>1</sub>=12; d<sub>2</sub>=14; n=4
H=10; H<sub>2</sub>=22; h<sub>1</sub>=7; b=5;
2-podshipnik uchun
D=72; D<sub>1</sub>=90; D<sub>2</sub>=110; D<sub>3</sub>=62;
d=9; d<sub>1</sub>=15; d<sub>2</sub>=20; n=4
H=12; b=4;
3-podshipnik uchun
D=80; D<sub>1</sub>=100; D<sub>2</sub>=110; D<sub>3</sub>=72
d=11; d<sub>1</sub>=18; d<sub>2</sub>=24; n=6
H=15; b=5;
Qopqoqni mahkamlash uchun vint tanlash
Bunda hamma qopqoq uchun standart ikkita vintdan foydalandim. Bu vint o‘lchamlarini standartdan qopqoq diametriga asoslanib tanlab oldim.
M6 va M10 markali vint tanlab oldim.
D=10; H=4; b=1.6; h=2; l=8…70(22)
Shlitsa tanlash
2-Val diametri d=58 ga mos 8x52x58 shlitsa tanlab oldim. O’lchamlarini jadvaldan oldim.
b=10; d<sub>1</sub>=49.7; a=4.89; f=0.5; r=0.5;
4-Val diametri d=78 ga mos 10x72x78 shlitsa tanlab oldim. O’lchamlarini jadvaldan oldim.
b=12; d<sub>1</sub>=69.6; a=5.45; f=0.5 r=0.5
